Organ transplantation requires a secure, transparent, and tamper-proof system to manage donor
registration, organ allocation, recipient matching, and audit trails. Traditional organ donation
management systems rely on centralized databases, which are vulnerable to data manipulation, lack
transparency, and may suffer from trust deficits among stakeholders. This paper proposes a Blockchainbased
Secure and Transparent Organ Donation Management System that ensures data integrity,
traceability, and fairness in organ allocation. The system leverages smart contracts for automated
matching and allocation, role-based access control for privacy preservation, and cryptographic
hashing for immutable record maintenance. A decentralized ledger records donor registration,
medical compatibility checks, waiting lists, and transplant confirmations. Experimental evaluation
demonstrates improved transparency, reduced risk of data tampering, enhanced traceability, and secure
multi-stakeholder coordination. The proposed system enhances trust among hospitals, organ banks,
government agencies, and recipients while maintaining regulatory compliance.
